As several other posters have commented, it’s ALL about LOCATION, not upgrades, when it comes to pricing in prime locations. Some friends recently looked at some coastal properties that had fantastic locations, were almost in the category of “fixers,” with no real upgrades, and even in this market, each property had three or four offers.
Upgrades seem to be what builders and sellers in less desirable locations offer to make the lack of location more attractive to potential buyers. Not really a deciding factor when it comes to those who wish to purchase real estate in a great location.
